Comptroller Scott Stringer has told city politicos that he’s certain to run for mayor if Mayor de Blasio is indicted by the feds — but will likely stay put if hizzoner is not charged by corruption probers.

“Scott is preparing to run, but part of that has to do with Scott’s feeling strongly the mayor’s going to get indicted,” one Democratic operative told
The Post. “If the mayor gets indicted he’s going to run. If he doesn’t, he’s going to wait.”

A city Councilman chuckled, “He’s been pretty open about it. In passing he’s said, ‘If the mayor goes down, I’m in.’ ”

Two separate state and federal investigations are looking into de Blasio’s fund-raising activities.

The state probe focuses on whether Team de Blasio broke state law through fund-raising efforts for state Senate races in 2014. The federal investigation is eyeing whether donors got favors for cash.

A de Blasio campaign spokesman said, “The mayor and the campaign . . . are fully confident that they have conducted themselves legally and appropriately at all times.”

Stringer, a Democrat, has amassed a $1.7 million war chest for a 2017 run. A Stringer spokesman declined to comment.
